Passports and Visas for travel
Visitors to Vietnam must have a passport with a minimum of one month’s validity beyond the planned departure date (and six months’ validity if arriving by plane).
Many travel agencies in Vietnam offer visa-on-arrival services at Noi Bai International Airport in Hanoi.
Free Wi-Fi is offered at most hotels and restaurants throughout Vietnam. The newer boutique hotels in Hanoi now offer laptops for in-room use. Internet cafés in remote areas like Sapa are hard to come by, but hotels usually have business centers or a Wi-Fi signal. There are plenty of Wi-Fi hotspots throughout the country, and most cafés and pho shops will lure customers by advertising an available connection. Be aware that there are government restrictions on social networking sites, so don’t be surprised if you can’t log on to Facebook outside your hotel room. To use your mobile phone abroad, find out if your cell phone carrier has a World Plan that offers roaming and coverage in Vietnam. A more affordable option is to unlock your cell phone and purchase a local SIM card in Vietnam, which will operate on local rates as opposed to international roaming fees.
